Specification of Letters Patent.

. Patented Feb.17,1920.

Application filed November 10, 1917, Serial No. 201,327. RenewedDecember 31, 1919. Serial No. 348,543.

To all whom it may concern:

Be it known that I, SAMUEL L. FISHER, a citizen of the United States,residing at Butler, in the county of Butler and State of Pennsylvania,have invented new and useful Improvements in Collapsible Furniture, ofwhich the following is a specification.

This invention relates to collapsible furniture and more particularly toa collapsible chair and has for its primary object to construct a chairof this character which when set up will have the strength and rigidityof a non-collapsible chair.

An object of the invention is the novel manner of connecting thedifferent parts so that the same will take up a minimum amount of spacewhen collapsed for shipment.

Besides the above my invention is distinguished in the manner of lockingthe parts and effectively holding the parts against independentvibration.

WVith these and other objects in view the invention will be betterunderstood from the following detailed description taken in connectionwith the accompanying drawings wherein:

Figure 1 is a side elevation of the chair.

Fig. 2 is a front elevation.

Fig. 3 is a plan view showing the parts collapsed.

Figs. 4, 5 and 6 are detailed views of the hinge connection between theparts of the back.

Figs. 7 and 8 are detailed views of the detachable connection betweenthe uprights and arms.

Figs. 9 and 10 are detailed views of the back.

Figs. 11 and 12 are detailed views of the brace.

Fig. 18 is another view of the chair when collapsed.

Fig. 14 is a detailed view of the strut.

Again referring .to the drawings the numeral 1 designates the back ofthe chair consisting of two parts, an upper part 2 and a lower part 3hinged together as indicated at 4 while the lower part is provided witha pin 5 adapted to enter a recess 6 in ihedupper part when the parts areassem- Passing through each part 2 is a bolt or pin 7 pivotallyconnecting the bottom 8 with the back in a manner to allow the bottom toswing toward and lay parallel to the back as clearly shown in Fig. 3.Also hingedly connected to the back as indicated at 9 are arms 10 eachprovided with a recess 11 partly closed by a plate 12. lVith the plate12 of each arm operates a. cli 13 on the up per end of an upright 14:,which is also pivoted to the forward part of the bottom as indicated at16, so that the uprights may swing into the proper position to lieparallel to one edge of the bottom and also to the back 1.

Swingingly connected to the bar 17 that connects the lower parts of theuprights together, is the threaded rod 18 of a strut 19, the nut 20 ofwhich has one end pointed so as to be inserted into a recess 21 in theconnecting bar 22- of the back. By this arrangement it will be seen thatby adjusting the nut on the rod 18 the back and upright are forced awayfrom each other with the result that the clip is prevented from movingout of engagement with the plate 12. Thus it will be seen that uponsimple adjustment of the nut 20 all parts are locked against movement.

If found an advantage in practice a brace 23 may be utilized. This bracehas a slotted connection 24 with the rod 18 and a pivotal connectionwith the seat or bottom as indicated at 25. Owing to the respectiveposition of the brace and rod 18 a binding action is accomplishedbetween the rod and walls of the slot 24 when the brace is forced in adirection indicated by the arrow.

It is to be understood that the structural embodiment of the inventionas a whole and its various features as shown are merely and means forlocking the heretofore mentioned parts against movement when the chairis assembled.

2. A collapsible chair comprising a two piece back hinged together, armshinged to the back, a bottom hinged to the back, uprights hinged to thebottom and having a lock engagement with the arms, and adjustable meansassociated with the bottom, back and upright for holding the sameagainst movement.

3. A collapsible chair comprising a two part back hinged together, abottom hinged thereto, arms hinged to the back, uprights pivotallyconnected to the bottom and having a lock engagement with the arms whenthe uprights are forced in a predetermined direction and an adjustableelement for moving the upright in said predetermined direction.

4. A collapsible chair comprising a two part back hinged together, abottom hinged thereto, arms hinged to the back, uprights pivotallyconnected to the bottom and having a lock engagement with the arms whenthe uprights are forced in a predetermined direction, an adjustableelement for moving the upright in said predetermined direction and abrace having a swinging connection with the bottom and a cam action withsaid element.

5. A collapsible chair comprising a back composed of two parts hingedtogether, a bottom hinged to the back, arms hinged to the back, uprightshaving a connection with the bottom and with the arms, an adjustablestrut mounted between the back and uprights and a brace pivotallyconnected to the bottom and having frictional engagement with the strut.

In testimony whereof I al'fix my signature.

SAMUEL L. FISHER.
